Perhaps you are understanding, and think these anti law people are not saying that we should not listen to Mt Sinai, as they put it, but that is exactly what they are saying. They are also saying that Christ did not complete the law at all, rather after He completed it, it was to be gone. They say that because Christ saves us from sin that the law describes, and because we have the Holy Spirit to lead us, we must not go to the written law ever.
They have understanding of Christ's forgiveness, of the two basic laws, of the Holy Spirit, that you talk of. They completely lack any understanding of where Mt Sinai fits into this picture and want it out. They say the truths you know and speak of wipes it out. In Galatians it says God will not be mocked, but they want God mocked when God dared speak to Moses.

There are three classifications of people - Jew, Gentile and church of God (which is the born again believer whether Jew or Gentile). Let's say I receive a letter from Tom written to Sue by accident and I didn't notice when I opened it and read it - I probably would have a look of confusion on my face reading it because what he has written to Sue does not pertain to me although I probably learned some things about Tom and Sue. It's the same way with the OT, we can learn a great deal from the OT and gospels but the church epistles pertain to me so there is where I look for my guidance. I can practically apply what is written there to my life now in the body of Christ. I cannot however apply OT law - speaking of THE WHOLE LAW - to my life. This is called rightly dividing the word of truth and if we do not then we have confusion and a lack of understanding.
For if that which is done away was glorious, much more that which remaineth is glorious. Seeing then that we have such hope, we use great plainness of speech: And not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished: But their minds were blinded: - Moses and the children of Israel did not see the WHOLE picture. for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ. But even unto this day, when Moses is read, the vail is upon their heart. And this happens to this day when people begin again to apply the OT to their lives day in and day out; they begin to become blinded to the liberty and freedom wherein Christ has set us. And no that does not mean I live life as I please . . . . I put off the old man, I put on the new man, I renew my mind so that I can be transformed and not conformed to this world - these are things I am told to do in the church epistles, among other great truths.
I pray "that Christ may dwell in your heart by faith; that you, being rooted and grounded in love, May be able to comprehend with all saints what is the breadth, and length, and depth, and height; And to know the love of Christ which passeth knowledge, that ye might be filled with all the fulness of God. Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us, Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.
Love in Christ, PB
